TECHNOLOGICAL FIELD OF THE INVENTION The present invention relates to an automobile tire pressure monitoring system (TPMS system), and more particularly to a TPMS system suitable for trucks that frequently change trailers. [Prior Art] 0 Tire pressure monitoring system has entered the field of cars, and the technology is more mature, but it is used less in the truck field. The reason is that truck trailers are frequently replaced, sometimes even changed several times a day, which leads to Items monitored in the truck system - tires are frequently replaced, making tire monitoring difficult. For this situation, most of the current practice is to install a receiver to monitor the trailer tires on the trailer, to install the receiver to monitor the front tires, and two to receive The machines are connected by wire, and the data is transmitted in a wired manner, and the data is transmitted to the display of the front display. When the truck is replacing the trailer, replace the wiring harness between the two. Although this method can solve the problem caused by the replacement of the trailer, the obvious drawback of this method is that a large number of wiring harnesses need to be arranged on the vehicle, and the installation is rather troublesome. Moreover, professional human intervention is required after the trailer is replaced to allow the system to update the monitored transmitter. This method is not only expensive to install, but also low in maintenance efficiency. In order to solve the above problem, US Patent Publication No. US 2 0 0 6 / 02 7 94 1 6 A1 proposes a tire pressure monitoring system that monitors a trailer by using a transponder (201043490 transponder) 21 in combination with an ID reader 13 Part of the tires. The code reader 13 is mounted to the rear of the vehicle head, and the transponder 21 is mounted on the trailer. The receiver of the front end transmits the information control transponder 2 1 ' through the code reader 13 to transmit the data to the code reader 13 by the repeater 2 1 , and the code reader 13 feeds back the relayed data to the receiver. This solves the problem of the connection line between the head and the trailer. However, this method still has the following disadvantages: 1. The system is more complicated, the front part of the vehicle needs to install the code reader and the trailer information receiving circuit, and the lead wire is required to the tail of the vehicle head, so the amount of the wiring harness installed in the front part is not significantly reduced; After replacing the trailer, you need to start the reader and read the tire ID information of the trailer part. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a more simplified and flexible tire pressure monitoring system.

[Embodiment] Since many trucks have the problem of trailer and front replacement, the tires of the same system are not fixed, that is, the tires monitored by the system are not fixed. However, relatively speaking, the tires of the front part and the trailer are basically not -8* 201043490. Therefore, according to one embodiment of the present invention, a tire pressure measuring system (TPMS) is proposed by setting a code registrar through no way. Registration is complete, and it is very easy to use the system to automatically identify the replacement of the trailer. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the arrangement of a tire pressure monitoring system according to an embodiment of the present invention. Fig. 2 shows a tire pressure sensing system (TPMS) structure according to an embodiment of the present invention. The tire pressure monitoring system is mounted on a vehicle 100 of a first component (e.g., a front portion 101) and a second component (e.g., trailer 102). The tire pressure monitoring system includes a registrar • a tire pressure transmitter 20 a of the trailer portion, a tire press 20b of the front portion, a repeater 30, and a receiver 40. Each tire pressure transmitter 20a, 20b - correspondingly mounted on each tire of the vehicle, is responsible for monitoring the pressure of the tire (there may also be temperature and sent out at regular intervals, when an alarm occurs, immediately send a data notification to the alarm 4). Here, The tire information transmitted by the tire pressure transmitter 20a is referred to as second tire information, and the tire information of the tire pressure transmitter 20b is referred to as first tire information. The first and second tire information includes tire pressure and tire identification (ID) Information, wherein the tire ID is qualified to correspond to the ID of each pressure transmitter. The information transmitted by the tire transmitter 20a of the trailer portion needs to be relayed through the repeater 30. The tire pressure transmitter 20b of the head portion can be directly sent to the receiving f. In the following description, the information transmission process of the tire pressure of the trailer portion will be emphasized. In an embodiment, as shown in FIG. 3, the register 10 is installed on the force monitoring line, and the automobile supervisor With part 10, the force is in the steam), the wheel of the receiver sends the actual pressure of the package, while the head of the I 40 is -9-201043490 101, which has a fixed This unique car registration number, the registration number and the timing of transmission. The structure of the register 10 is as shown in FIG. 2, and includes a controller 11, a signal transmitting unit 12, and a battery power supply circuit 13. Registrar 10 is powered by a lithium battery. The design controls the transmit power of the registrar 1 , so that its coverage is near the receiving antenna 3 1 of the repeater 20 of the system to ensure that the repeater can reliably receive the registration code, while the repeaters of other vehicles Cannot receive the registration code. The Registrar 10 uses a large capacity battery to achieve a working life of up to 10 years. In another embodiment, the registrar 10 can also send a registration code to the receiver 40 to provide registration. In yet another embodiment, the Registrar 1 can also be a stand-alone handheld device that is sent by the operator to the repeater 20 when needed. Referring to FIGS. 2 and 4, the repeater 30 includes a central controller 32, a transmitter signal receiving unit 33, a registrar signal receiving unit 34, a signal transmitting unit 35, a power supply circuit 36, a standard air pressure setting circuit 37, Circuitry such as reading unit 38. The repeater 30 is mounted on the trailer 102, and is connected to the normal line power of the trailer portion, and is responsible for forwarding the second tire information transmitted by the tire pressure transmitter 20a of each tire on the trailer 102. The repeater 30 needs to be registered by the register 10. After working properly. Specifically, the repeater 30 receives the registration code information sent by the registrar 10 through the registrar signal receiving unit 34, and after the registration is successful, the repeater 30 monitors the second tire information (for example, the tire ID, The tire position, tire standard pressure 値, tire pressure, temperature, etc.) and registration code information are sent to the receiver 40 via the signal transmitting unit 35. The transmission process is roughly as follows: the repeater 30 receives the wheel -10- 201043490 tire information from the tire pressure transmitter 20a via the transmitter signal receiving unit 33. The reading unit 38 of the repeater 30 reads the tire ID information of each tire of the trailer section. In one embodiment, the tire 1 D information corresponding to each of the transmitters 2A can be stored in the corresponding ID code information body (such as the ic card mode), and inserted into the reading unit after the transmitter is installed. 38 for reading the reading unit. The reading unit 38 can be configured in a combination of hardware and/or software. When the repeater 3 receives the second tire information, the central controller 3 2 extracts the tire ID information and compares the tire ID information read by the self-reading unit 0 3 8 to be consistent with the signal transmitting unit. 35 is sent to the receiver 40, and if not, it is discarded and is not processed. Preferably, the repeater 30 has a function of setting a standard air pressure. The standard air pressure setting circuit 37 is used to provide an interface for setting the standard air pressure of each tire. The tire pressure standard 値 is set when the tire needs to set the standard pressure 値 (such as the first installation of the transmitter and the replacement of the transmitter), etc. 'First fill the tire pressure to the standard pressure, long press the setting of the repeater 30 Q button for 5 seconds, the repeater can be placed in the standard air pressure setting mode, at this time the tire pressure is charged to the standard tire pressure, after which the relay receives several frames of data according to a certain algorithm (eg: average値) Derived the standard pressure for each trailer tire. In actual operation, after the repeater 30 is activated, information such as the tire ID information and the set standard pressure 各 in each ID code information memory is read. Then, the repeater 30 waits for the registration code to be received, enters the normal monitoring mode after receiving the registration code, and immediately sends all the monitored second tire information, and the registered tire code is attached to the monitored tire information. After that, the second tire information monitored by -11 - 201043490 will be forwarded once. Referring to FIGS. 2 and 5, the receiver 40 is mounted on the front end including a central controller 41, a power supply circuit 42, a transmitter signal unit 43, a repeater signal receiving unit 44, a reading unit 45, a display 46, and a standard.

An ID code information memory (not shown) corresponding to the head portion 2〇b and a tire pressure transmitter 20b of the head portion can be mounted on the reading unit 45 in the receiver 40. Specifically, the first tire information from the tire pressure is received by the transmitter signal receiving unit 43. When the receiver 40 receives the first round, the central controller 4 extracts the tire ID information and compares the tire ID information read by the self-unit 45, and the vehicle tire information processing is retained if it is consistent, and if not, the disc is discarded. The standard gas circuit 47 similar to the repeater 30 is also disposed in the receiver 40 for setting the standard tire pressure of each tire of the head portion. The receiver 40 may contain a registration code that is associated with the Registrar 1 to identify the identification of the signal transmitted by the repeater. The registration code can be in the receiver or can be obtained by registering with the registrar 10. The booklet 10 can be fixed to a certain part of the front of the vehicle or can be a handheld device. Referring to FIG. 6 'when the receiver 40 receives the tire information including the registration code sent by the repeater 30 via the repeater signal connection 44, 201, the registration code is extracted (step 202), and the registration is self-registered. The code is compared (step 203) 'if it is consistent, it indicates that the receiving single unit transmitter is connected to the monitor on the 101 and is used as the pressure setting, as the receiving unit preset in the note (step Save this round -12 - 201043490 The tire information is the information of the currently trailer, record the trailer tire information monitored by the repeater, and process the tire temperature/pressure information sent by the repeater 30 (step 204). For example, it is transmitted to the display unit 46 for display, so as to realize the monitoring of the whole vehicle tire. If the registration codes of the two are inconsistent, it is considered that the tire information of the currently-mounted trailer is discarded, and when the trailer is replaced, there is no need to replace the trailer. The tire 30 and the tire pressure transmitter 20a, the system automatically completes the tire ID information update by the second tire information including the registration code sent by the repeater, and according to the new group The system is monitored. In summary, the embodiment of the present invention proposes a solution for the truck tire pressure monitoring system that frequently replaces the trailer, which can automatically identify the tire pressure transmitter identity replacement brought by the replacement of the trailer, and automatically adjust the system. The system can automatically monitor the new tire pressure transmitter. Compared with the current solution, the proposed solution has the following advantages: 1. Automatic registration of the code using the registration code transmitter, so that the monitoring process is fully automated No human operation is required, the user does not need to operate very professionally, reduce the possible errors of the manual code, the use is simpler and more convenient, and the whole process is automated, so that the maintenance cost during the user's use is reduced, and the vehicle is improved. The efficiency of use 2. Because the wireless connection method is adopted between the repeater and the receiver, the installation is very simple, and a large number of wire harnesses are reduced, and the hardware cost and the installation labor cost are reduced. -13- 201043490, in order to achieve the above objects, features and DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed description of the embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein FIG. 1 is a schematic diagram showing the arrangement of a tire pressure monitoring system according to an embodiment of the present invention on a vehicle.
